I bought a Troy Alpha handguard, but the box came with rail sections for the Troy V-TAC handguard. I have one 4.2" rail and two 2" rails, plus backs and screws. They've never been installed on a rifle. I did try to fit the 4.2" rail into my angled grip, so there is a small smudge on it. Anyone have a need for these parts, since I don't? I would prefer to get rid of all three at once, rather than separate. $40 cash or trade for a few 20rd boxes of 5.56 ammo? FTF in Beaverton/Hillsboro area. I could be talked into doing Paypal and shipping them...maybe.
